Additional Microphones for ReSpeaker Core v2


for my project I need to expand the ReSpeaker Core v2 by at least two additional SMD microphones, around 2m away.

Since I want as few additional components as possible I think I2S or I2C is the way to go.

I do not need all of the microphones at the same time. (Either my added ones or the original installed)

As far as I see the I2S are not accessible from external.

Is there a way to achieve this?



Hi Miguel

Please cut the 2 call back channels and connect to you 2 mics. thanks.
